INSTRUMENT FOR ATTAGEING- BUTTONS TO FABRICS The Schedule referred to inthese Letters Patent and making part of the name.

new and improved Tool, on the compression principle,

to Secure our Patent Buttons, patented December ,31, 1867, to Materials;and we do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

The nature of our i vention consists in providing two or more dies or pates, of a thickness that will readily pass between the button and theflange, onthe cylindrical shank, so that they may .act on thecylindrical shank alone, and not disturb either the flange or thebutton.

We construct our tools chiefly with two blades. These blades have each agroove through the edges", that come'together. The mouth of thesegrooves is j s 1 rgs..-en0ugh fertile cylindrical shank. to enter. Thebottom of the grooves is rounded out, to form a half circle, of a sizethat the shank is desired to be compressed to, fitting and securelyattaching it to the diminished form of rivet within it. The'sides of thegrooves taper equally from the mouth of the grooves to the semicircles.

These blades are also constructed to lap each other, that is, half ofone'of the blades is removed, and the opposite half of the other is alsoremoved to fit the projecting parts, that the plates may come togetherin the same plane, bringing the two semicircles together, formingacircle, and presenting the appearance of a hole through a solid plate.

The object of theseplates being constructed in this peculiar way is, tomake the labor of compression easy, by distributing it, and to compressthe shank equally and alike all round, without making a burr, or defacing the shank, so that the button-hole may not be cut in wearing it.

For compressing the shanks of buttons, these plates may be pressedagainst each other in many ways that of attaching the blades to apincers shaped tool being 'a simple and effective way. The plan we findmostsatisfactory is, to attach one of the blades permanently to theframe of the tool, the other to amovable piece that works in a slot inthe frame, and has one end projected into an upright inclined plane.There is a'movable lever hinged to the frame-piece, that has a roller init, which'works against the inclined plane, forcing the sliding piece,withmovable blade, against the stationary one. On removing the power,the sliding piece is.forced back by means of a spring.

We also construct tools for attaching our patent buttons, where morethan two blades are used, to 'compress from different points, and lessenthe liability of forming a burr on the shank. I

We also construct tools, as shown in patent, No.

' 72,929, granted to us, where simple blades are used,

that do not lap, and have not the tapering grooves, but merely buttagainst each other, and havesimply semicircular grooves. I

We have also eflected the compression of the shank of our button by atool, with rollers in it, to come in contact with the shank, and rollthe compressiongroove, instead of forcing it in with direct action ofdies.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construction and operation, referring tothe drawings, which .form a part of these specifications.

We construct a frame-piece, marked AA, in Figures 1 and 2., This pieceis so constructed that the stationary blade or die, B, can bepermanently attached, and also. to form a guide for the sliding blade 0.This piece is also extended to form a needle-box, and one of thehandles, as shown at A. There is cast on this frame-piece a lug, asshown at D, to which is hinged a second handle, E. This handle isprovided with a roller, as shown at F. This roller operates against aninclined plane, G, which forms a part of the sliding piece H, to whichthe sliding blade 0 is attached.

The tool is operated by forcing the handle E to wards the handle A, thuscausing the roller to rotate on the inclined plane, and force thesliding piece and blade to meet. the stationary one. On removing thepower applied, the spring S forces the sliding piece to its formerposition.

The blades for compressing the shank of the button are constructed asfollows:

Each blade has a corresponding groove, as shown at h h. These groovesare widest at the mouth, as shown at M, in the groove h, tapering-to thesemicircle. m.

The blade 0 is the same shown at e c, tapering to m. -A part of theupper part of the blade B is removed'toh'alf of its thickness, as shownat t t. A corresponding lower part of the blade 0 is also removed, asshown by dotted line at v v.

To bring these blades together in closing, the upper projecting part. ofsliding blade, at b b, fills the recess of the upper part of stationaryblades, shown at t t. The lower half of these blades is vice verse, andwhen the blades are closed, the two semicircles m m come.

together, making a circle, forming. as it were, a hole through a solidplate.

The blades operate this: The shank of the button is admitted into thedie through the opening 0, until it touches at a. The. blades not closeround the shank as power is applied to the handles. The shank being thesame diameter as the mouth of the grooves, it just enters them, and oncontinuing the power, the inclined sides compress the parts of the shankthat come in contact with it. Thus, by the time the semicircles areremixed, more than half of the compression is accom plished. At thispoint more power is gained to finisl the compression, by-a less angle ofinclination in the inclined plane onthe sliding pieoe. Thus, the shankof the button is equally compressed all round, without defacing it.

We also construct the flame-piece so as to form a.

needle-box, as shown at P. The needle is kept in its place by a plugbeing screwed in the opening.

What we claim as our invention and desire to see cure by Letters Patent,is-- i 1. The bed-piece A, lever E, friction-roller F, slidi112 dieplate 0, attached to and operated by sliding piece H, having an inclinedface, and a stationary dieplate, B, combined and arranged substantiallyas herein described and. for the purposes set forth.

2. The die-plates B and C, so constructed, with'removed surfaces t t anda: 1:, that they may overlap, and their dies provided with inclinedsides 6 1 and e e','coxnbined and operated substantially as hereindescribed.
